Natural polymers (from the Greek poly meaning "many" and meros meaning "parts") are found in many forms such as horns of animals, tortoise shell, shellac (from the lac beetle), rosin (from pine trees), asphalt, and tar from distillation of organic materials. The term polymer is commonly used in the plastics and composites industry, often as a synonym for plastic or resin. So a crystalline polymer really has two components: the crystalline portion and the amorphous portion. 3 POLYMERS - CLASSIFICATIONS - Thermosets: cross-linked polymer that cannot be melted (tires, rubber bands) - Thermoplastic: Meltable plastics - Elastomers: Polymers that stretch and then return to their original form: often thermoset polymers - Thermoplastic elastomers: Elastic polymers that can be melted (soles of tennis shoes) • Polymer Families - Polyolefins: made from olefin. A SILENT REVOLUTION. Therefore, by combining the individual advan-tages of starch and synthetic polymers, starch-based completely biodegradable polymers (SCBP) are potential for applica-.
